Struct SacActorConfig 

pub struct SacActorConfig {
    pub num_layers: usize,
    pub hidden_dim: usize,
    pub use_orthogonal_init: bool,
    pub activation: BurnActivation,
    pub seed: Option<u64>,
}

Configuration for the SacActor architecture.

Analogous to crate::policy::mlp::MlpBurnConfig: depth, width, activation, an orthogonal-vs-Kaiming init toggle, and an optional construction seed for bit-exact reproducibility.

Fields

num_layers: usize

Number of hidden layers in the shared trunk. Only 2 or 3 are supported; anything else is treated as 2 (matching crate::policy::mlp::MlpBurnConfig).

hidden_dim: usize

Width of every hidden layer.

use_orthogonal_init: bool

If true, initialize hidden-layer weights with Initializer::Orthogonal (gain sqrt(2)) and the output heads with gain = 0.01. Set false to fall back to Burn’s default Kaiming-uniform init.

activation: BurnActivation

Activation applied between hidden layers.

seed: Option<u64>

Optional construction seed. When Some, SacActor::with_config builds every layer from a deterministic, StdRng-driven weight buffer (see crate::policy::seeded_init) so two constructions with the same seed produce bit-identical actors. When None (the default) Burn’s unseedable Initializer path is used verbatim.

Implementations

impl SacActorConfig

pub fn with_seed(self, seed: u64) -> Self

Set the construction seed, enabling the deterministic host-side init path in SacActor::with_config.

Builder-style; returns self for chaining: SacActorConfig::default().with_seed(42).

Trait Implementations

impl Clone for SacActorConfig

fn clone(&self) -> SacActorConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for SacActorConfig

impl Debug for SacActorConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SacActorConfig

fn default() -> Self

Returns the “default value” for a type.
